Moving In with Boyfriend… next year

My boyfriend and I have been dating for 2 months.

Not long, I know, but when you know, you know.

We are both 23, he makes very good money and I make okay, enough to get by.

Recently he brought up how he’s looking at buying a home, a place to live for 10+ years and he brought up, in the long run, that’s where he wants us to live.

He specified he was hoping next spring we would be moving in together in a home he bought.

We spoke further and decided that a test run in the place he is renting would be best before investing in a home.

The catch is I live at home, and my parents, my mom is more vocal about it, are against living together before marriage.

I am unsure how they would react to this decision, even one so far in the future.

My mom doesn’t even want me spending the night there, despite him staying over with us.

I believe a large part is her being overprotective. I was SAd by and ex in college and I don’t think she ever moved passed it.

What would you do? Is this a smart choice?

Just to spec, we are not moving in together now. It would be in a year at the earliest.
